SPRING BED-BOTTOM.

Specification of Letters Patent.

Patented April 9, 1907- Application filed May 9, 1906. Serial Nc.315,913.

vuseful Improvements in Spring Bed-Bottoms, of which the following is aspecification.

This invention relates to improvements in spring bed-bottoms, the objectof the invention being to provide a bed-bottom of this character whichis susceptible of being folded in close compass for storage ortransportation and which embodies novel and improved means forconnecting the parts orv sections thereof and securing an effectivespring action and a proper tensional resistance to sagging. l

In the accompanying drawings, Figure 1 is a top plan view of a springbed-bottom constructed in accordance with my invention. Fig. 2 is a sideelevation of the saine. Fig. 3 is a transverse section through the frameon line 3 3 of Fig. 2, omitting the coupling-bars and the bed-bottom.Fig. 4 is a vertical longitudinal section. Fig. 5 shows in full lines abottom plan view of one of the frame-sections as it appears when foldedover upon the companion section and in dotted lines a top plan view ofthe same when unfolded or turned back to operative position. Fig. 6 is aside view of the folded frame. Fig. 7 is an outer end elevation of oneof the frame-sections.

Referring now more particularly to the drawings, the numeral 1designates the bedbottom proper, which is preferably made of woven wire,but may be formed of any other suitable material and which istransversely divided at its center to form sections 2 and 3, united attheir inner or meeting edges by a hinge or pivot 4, so that one sectionmay be folded over upon the other and in parallel relation therewith forconvenience in storing or transporting the bottom. .The bottom 1 iscarried by a supportingframe consisting of two similar sections 5 and 6,eaehof said sections comprising side pieces 7, an outer`end piece 8, andan inner end iece or cross-bar 9, the whole preferably consisting of asingle casting, although each section of the frame may be constructed inany preferred way. The inner or meeting ends of the side pieces 7 of thesections are hingedly or pivotally connected at 10, so that one sectionmaybe folded'over upon the other as shown in Fig. 6, thus enabling thecomplete bed-bottom to be packed in close compass. The side pieces 7 andend piece 8 of each frame-section are preferably made of angle material,the upper webs 11 thereof being horizontal and the lower webs 12vertically disposed.

In order to hold the frame-sections 5 and 6 in extended position andlongitudinal alinement, the side pieces of each section are providedadjacent their inner ends with keeperloops 13 to-receive a coupling baror member 14, slidably adjustable therein, one end of said bar having aninwardly-bent portion 15 to engage the adjacent side piece of one of theframe-sections, while the other end thereof is apertured for thereception of a pin 16, carried by or adapted to be inserted within anopening in the adjacent side piece of the other frame-section to holdthe bar 14 in applied position. The part 15 on one end of thecoupling-bai' forms a stop to engage the adjacent guide-loop 13 to holdthe bar from endwise movement in one direction, so that in order todisconnect the bar to permit the frame-sections to be folded the pin 16must be removed and the apertured end of the bar successively slid outof engagement with the keepers by a longitudinal movement of the bar inthe reverse direction, thus leaving two sections free to swing upontheir hinged connections 10. The bars 14 when applied across the meetingends of the side, ieces of the sections thus firmly and secure y holdthe latter'from movement.

Upon the outer ends of the frame-sections are mounted brackets 17, eachcomprising a head-piece 18, which is horizontally arranged and has atits inner end a depending vertical flange 19, the head-piece also beingprovided -at its ends with depending legs or standards 20, fastened tothe side pieces 7 of the framesection by screws 21. An intermediateconnecting-piece 22 abuts against the outer surface of the flange 19 andextends downward through an aperture 23 in the horizontal flange or web11 of the end piece 8 and is fastened to the vertical flange of said endpiece by a bolt or other suitable securing device 24.

The ends of the bed-bottom 10 are provided with coupling members 25,formed with apertures to engage hooks 26 on transverse supportingplatesr members 27, normally arranged to bear against the inner faces ofthe flanges 19. Passing through each of the said plates 27, the ,flanges19, and

outer side of the Web 12 a the intermediate connecting-piece 22 at eachend of the frame is a series of connecting bolts or rivets 28, which arefreely slidable in the parts 19 and 22 and are connected at 5 theirouter ends with an outer cross piece or plate 29, which is thus movablewith the cross-plate 27. Surrounding the pins or bolts 28 between the:flange 19 and plate 29 and at an intermediate point between theconnection 22 and plate 29 are sleeves 30, formed of rubber or othersuitable elastic material and which serve by their expansive tendency toforce the plate 29 outwardly, and thus draw upon the plate 27 to exerttension upon the bed-bottom 1, the sion devices thus constructed at theend portions of the frame serving opposite directions upon thebed-bottom to hold the same stretched to thev desired tension and toeffectually prevent sagging thereof. To all intents and effects theelastic sleeves 30 thus serve the function of springs, and it Will beunderstood that in lieu thereof coiled springs may be employed.

Arranged below the'respective inner ends of the sections 2 and 3 of thebed-bottom 1 are transverse supporting-plates 31, from which dependguide-pins 32, which are itted to slide vertically in openings 33 in theinner cross-bars 9. Surrounding these springs between the bars 9 andplates 31 are coiled cushioning-springs 34, which serve to hold theplates 31 normally pressed upward -to yieldingly support the centralportion of the bed-bottom and prevent sagging thereof at the point whereit is subjected to the greatest pressure .and strain. The pins 32loosely fit Within the openings 33, so that when the bed bottom 1 isdisconnected from the brackets 18, which may be done by removing thecoupling-plates 25 from engagement with the hooks 26, the plates 31,pins, and springs may be detached from the bed-bottom frame.

will be yieldingly supported and that provision is made at the ends ofthe frame for automatically maintaining the same under a desired stretchor tension.

The frame of the bed-bottom is made to suit bedsteads of a prescribedsize and te rest in the usual manner upon the ends of the slats abovethe retaining-rails or directly u on said rails but in some cases theWidth oli) the bedstead may be greater than that of the bed-bottomframe. In order to overcome the difliculty of applying the bed-bottomunder such conditions, I provide adjustable fastening means forconnecting the bedbottom frame with the bedstead frame. These fasteningsare mounted upon the vertical webs 12 of the side pieces 7 of eachframe-section, and each consists of a pivoted hook or button-plate 35,arrangedupcn the two sets of tento exert a pull in It will thus be seenthat the bed-bottom nd pivotally mountl ed upon a fastening pin or rivet36, passing through said web and the intermediate porl tion of a bowedspring 37, having its ends bearing against the inner face of the web.'l`hc hooks 35 are adapted to engage the upper edges of the side railsof the bedstead and through the medium of the spring 37 and thefastening-pin 36, which is slidably and pivotally mounted in the openingin the l web thrcmgh which it extends, the hook may be drawn out fromthe side piece 7 a greater or less distance, according to the width ofthe frame of the bedstead, tocngage the adjacent side rail thereof, sothat the hooks upon the frame when in engagement with the two side railsof the bedstead will hold the frame in applied position, the tension ofthe springs 37 serving to hold the parts in firm engagement.

Figs. 1, 2, and 3 show the bed-bottom set l up for use. When it isdesired to collapse the same for storage and transportation, the fbottom proper, 1, is disconnected from the hooks 26 and one of thesections of'the same folded over the upon other, after which thesupporting-plates 31 and cooperating parts are detached from the frameand the brackets 18 then disconnected from the frame by rel moving thebolts 24 and fastening-screws 21, one of the sections of the frame thenbeing n folded over upon the other, as shown in Fig. 6. Theretaining-plates and springs 32 and the brackets 18 and applied partsmay then be inserted in the space between the bars of the foldedframe-sections, the folded bottom folded frame, and the commanner. Thebed-bottom when thus collapsed will occupy but a small space and may beconveniently stored or shipped.

Having thus described the invention, what is claimed as new isj 1. Aspring bed-bottom comprising a folding frame, said frame embodyinghinged sections, each composed of side pieces and outer and inner eri-dpieces, yielding tension devices upon the outer end pieces, said tensiondevices being provided with hooks, a folding vbed-bottom proper composedof hinged sections and provided at its ends with coupling members toengage said hooks, cross-plates applied to the sections of the bottom onopposite sides of its joint, guide-pins carried by said plates andslidable vertically in the inv ner end pieces of the folding frame, andsprings encircling said pins between said plates and end pieces.
